WHEEL.

will vbe cheap and easy to` manufacture,

which will have a small number of parts, being only two principal partsin number; which shall be easy to lubricate because there will be nonecessity for removing the ca'p or wheel; which can be formed by dieswithout machine work, and which will do away with tlie-brea age of thewire spokes in that type of, wheel; which will not be subject to thelooseningv of spokes or the shrinkage thereof `as in wooden wheels;which will have no threads to wear out, no springs, and

-yet will be as strong and resilient as a wooden wheel; which will beeasy and convenientto make on account of being smooth and free frombolts, rivets, etc., and which will have allparts readily accessible;also to provide a 'wheel' which will be so constructed that the additionof the Outer rims and hub 'flanges will strengthenfit and preventpossible loosening of the parts of the wheel, and which will have therin'i and hub integral with leach other, thus requiring no ysleeves orfastening devices to keep theparts ofthe wheel together.4 Furtherobjects and advantages of the invention will appear heieinafter.

Reference is to be had to the accompanying drawings in which- Figure 1is a side elevation of a portion of a Wheel constructed in accordancewith this invention,.and g Fig. 2 is a sectional view on the line 2 2 ofFig. 1 longitudinally through one ofthe okes.

The wheel itself consists of two members of pressed metal A and B. Eachof these members is adapted to be pressed out by ordinary metal pressingprocesses without serious complications, and without thinning the metalat any point so as to weaken it.

`Each one of'these parts is of circular form and is providedlwitha'central hub portion,

Specification of Letters Patent.

' Application led April 29, 1916. Serial No. 94,464,

a felly portion, a web portion compris? ing spokes. The centralportionhas a rigid hollow cylindrical part for the reception of the hub, andthe felly portion has a cylindrical part for the reception of the removable riin C.

The spokes are of coursepressed out with the .rest of the two blanks,and it-is preferred to have the spokes of the two parts A and B directlyopposite each other so as to register. These spokes are preferablypiovided Ywith longitudinal'or radial strengthening ribs a, b which areformed by pressing the metal outwardly. f

At the center each of these members is pressed inwardly to form twoconcentric hub flanges a and b of the same diameter. These two comesubstantially together. at the cent-er so as to complete the hub andconnect the two members at that point. The

way shown for connecting them is to offset them outwardly so as to form'two cylindrical flanges c2 and b2, one fitting inside the other. Theseflanges are then secured to` gether preferably by electrical welding sothat the two members A and' B are firmly united at the center. This alsoleaves a cir! cular oil groove D which will receive oil in the usual wayand provide the desiredy lubrication for the bearing balls with whichthe hubs will' ordinarily be provided. No'

hiib shown as that does notconstitute a part of this invention.y

At the circumferencea similar construc-T tion is provided, the twomembers A and B having cylindrical flanges, c3 and o3, onel fitting inthe ot-her throughout their length aiid preferably electrically weldedtogether. One of these flanges, in the form shown the one marked b3, isprovided with an outward circumferential bend b4 designed to form oneend of the seat for the metallic rim C. This is secured on thepther sideof the wheel by a series of clamp plates E each projecting in betweenthe rim C and the flange b3. These clamp plates are held in' position bybolts F. It will be noticed that while these bolts are employed they arenot used to hold the wheel itself together but only to clamp the rim inplace. For the purpose of making this construction more rigidat thispoint and especially to prevent the tightening up of these bolts withoutany distorting effect on the wheel an inner felly G is provided formedof a ring of wood. This lits description is given here of the particularamount of metal and with the metal in its4 simplest form, and the other,advantagesA above mentioned are also secured as will be obvious, .Byhavmg each spoke: straight andfseparated widely, they are renderedL ex-`tremely rstrong and light.: y i; AilthQugh-I have illustrated and..described only@ ia `single' Aembodimenty ofv the invention I am aware ofthe fact that modificationsk can be made-@therein by any personfskilledLinA tl1e:artwithout departing from the scope" of theinventionais-expressed in the cial-nis.l

Therefore I do not wish to be limited yto all the details ofconstruction herein shown'and described, but what I do claim is l 1. Asan article of manufacture, a com-f' plete wheel frame consisting of twoparts, eachl of said parts consisting of a single 25 pressed metalmember having a cylindrical hub flange, a plurality of spokes, and acylindrical felly flange all integrally connected with each other, thetwo felly flanges fitting one'within the other and secured together' andthe two hub flanges fit-ting one within the other 'and secured totheinner surface of the other. v

2. As an article of manufacture, a com-v plete wheel frame consisting oftwo parts, each of said parts consisting of a single pressed metalmember having a hub portion, a felly portion,v and a web portion, allintegrally connected with each other, the two I felly portions havingcylindrical flanges, r"40 one outside the other and secured yto theouter surface of the other, and ythe outside one having acircumferential side. projection continuous with the felly portion onthat side and inclosing the edge*l of the opposite felly flange forreceiving the edge of a removable rim.

- 3.As an article of manufacture a complete wheel .frame consisting oftwo parts.

each Aof said parts consisting of a single pressed metal member having ahub portion, a plurality of 'spokes,an=d a felly portion, allnintegrally connected with each other, one of said two parts beingsubstantially flat from the end of the felly portion to the end of thehub portion, and theotherbeing substanl tiallyconical, all vthe lspokesbeing substantially straight throughout their lengths and entirely outof contact withrthe spokes on,V the opposite side ofthe wheel. e

4. As an articl'e16f manufacture, a wheel 60 consisting of twopal'ts,'e`achof. said partshaving a hubportion, a felly portion, and awebgportiom said hub portionsbeingof the same diameter at their ends,each being pressed outwardly and then overlapping arid secured togetheron va circle having a larger diameter so as to forni anl oil groove atthe center of the hubportion.

5'. As an article of manufacture', a wheel consisting of two parts, eachof said parts having a hub portion, a felly portion, and a plurality ofspoke members, all integrally connected with each other, the two fellyportions having cylindrical flanges, one outside the other and welded tothe outer surface thereof, the outside one having a circumferential sideprojection for receiving the edge of a removable rim, series of clampson the other side of thewheel for holding said rim, and a wooden ringinside the felly against which said clamps are secu-red.

6. As an article ofpmamifacture, a wheel consisting of two parts, eachof said parts comprising a single pressed metal member, one having acircumferential side projection for receiving the edge of a removablerim,

a series of clamps on the other side of the wheel for holding said rim,and awooden ring inside the felly aga-inst which said clampsare-secured. I

In testimony whereof I have hereunto set my hand. i
